An organic light emitting display panel

Abstract

The invention discloses an organic light emitting display panel. Wherein, the organic light-emitting display panel includes: a substrate; a plurality of anode electrodes formed on the substrate in an array; a pixel definition layer formed on the substrate, and at least partly exposed to the anode electrodes, thereby defining a plurality of anode electrodes respectively corresponding to each anode The effective light-emitting area of ​​the electrode and the non-effective light-emitting area around the effective light-emitting area; the partition pattern is formed on the pixel definition layer and at least partially surrounds the effective light-emitting area; the organic light-emitting layer is formed on the anode electrode, the partition pattern and the pixel definition layer On: the cathode layer, formed on the organic light-emitting layer, wherein the partition pattern isolates the organic light-emitting layer and the cathode layer in the effective light-emitting area from the organic light-emitting layer and the cathode layer in the non-effective light-emitting area. Through the above method, the present invention can reduce the light leakage caused by the lateral conduction of the organic light-emitting layer, thereby improving the display quality of the panel.

Description

technical field [0001] The invention relates to the field of display manufacture, in particular to an organic light-emitting display panel. Background technique [0002] Organic Light Emitting Diode (OLED), because of its characteristics of self-luminescence, fast response, wide viewing angle, etc., OLED-based organic light-emitting display has become a mainstream product in the display field. [0003] Among them, when the manufacturing process of the light-emitting layer is full-surface evaporation, due to the need to balance the material life and other factors, the light-emitting layer may have lateral conduction, which will be reflected on the panel as light leakage, which will further reduce the display quality of the panel. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide an organic light-emitting display panel, which can reduce the light leakage caused by the lateral conduction of the organic light-emitting...

Problems solved by technology

[0003] Among them, when the production process of the light-emitting layer is full-surface evaporation, due to the need to balance the life of the material and other factors, the light-emitting layer may have a lateral conduction, which is reflected on the panel as light leakage, which in turn will reduce the display quality of the panel.
